Every Saturday and Wednesday from 1-5 there is a farmer's market here in Carlsbad. Recently I have found myself only making it to the Wednesday market. Partly because I originally thought the market was weds and sun, and partly because there are people to spend time with on the weekends instead of wandering around the market.
Some of my favorite items to purchase at the market are zucchini, avocados, potatoes, corn, and prickly pear. If you haven't tried a prickly pear I highly suggest it the next time you are at your local farmer's market. They taste a little like guava and a little like a mix between a pear and a banana. They have seeds like a pomegranate inside the flesh which you can just swallow.
The other highlight of our new place are the grapes and blackberries growing in the back. I'm not exactly sure what to do with the grapes as they are very small, sweet flesh, sour skin and have little seeds inside. With the blackberries I want to try to take a cutting and see if I can grow them on the front porch. That way they would get more sun and would turn from red to black and probably be more sweet.
Lastly in the front of our house we have a grapefruit tree. Sadly they are not ruby red grapefruits but rather large yellow ones. We pulled one off the tree the other day to try it and despite the super thick rind, the grapefruit inside was pretty tasty. A little sour to eat the whole thing but probably good for making grapefruit juice.
